First Impression

U2OTGSD looks like just a USB-microUSB cable, but supporting three functions in a small cable; 1. USB2.0-microSDXC Reader for PC,
2. USB2.0 OTG-microSDXC Reader for smart phone,
3. USB2.0-Link/Charge Cable between PC and Smart Phone.

A single cable works as not only using USB-microUSB cable between PC and smart phone, but also the cable itself will be microSD card reader for both PC and smart phone.
